x^2+y^2<= 25

x^{2} + y^{2} \leq 25

(a, b) = (0, 0), r = 5

Solution steps

x^{2} + y^{2} \leq 25

Rewrite

x^{2} + y^{2} \leq 25

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 5

2 x^{2} + y^{2} = 2

(x - 3)^{2} + y^{2} = 4

y = - 4 x^{2}

\frac{x ^{2}}{25} - \frac{y ^{2}}{9} = 1

x^{2} - 2 x - 4 y + 9 = 0
